AI总结:

本研究针对机器人辅助食管切除术构建了大规模语义分割数据集,通过在RAMIE和CholecSeg8k数据集上对八种实时深度学习模型进行基准测试,发现基于ADE20k预训练的注意力模型(如SegNeXt和Mask2Former)在手术场景分割中优于传统CNN。

摘要:

食管癌是全球最常见的癌症类型之一。传统上采用开放式食管切除术进行治疗,但近年来,机器人辅助微创食管切除术(RAMIE)已成为一种极具前景的替代方案。然而,机器人辅助手术对新手外科医生而言颇具挑战,因为他们常会丧失空间方向感。计算机辅助解剖识别有望改善手术导航,但该领域的研究仍然有限。在本研究中,我们为RAMIE中的语义分割开发了一个综合数据集,其中包含迄今为止最大量的重要解剖结构和手术器械集合。处理这种多样化的类别集带来了挑战,包括类别不平衡以及神经等复杂结构的识别。本研究旨在了解当前最先进的算法在此新数据集和问题上的挑战与局限性。因此,我们使用两个预训练数据集对八种实时深度学习模型进行了基准测试。我们评估了传统网络和基于注意力的网络,假设基于注意力的网络能更好地捕捉全局模式,并解决由血液或其他组织引起的遮挡等挑战。该基准测试包括我们的RAMIE数据集和公开可用的CholecSeg8k数据集,从而能够对手术分割任务进行全面评估。研究结果表明,在ADE20k(一个语义分割数据集)上进行预训练比在ImageNet上预训练更有效。此外,基于注意力的模型优于传统卷积神经网络,其中SegNeXt和Mask2Former取得了更高的Dice分数,且Mask2Former在平均对称表面距离上表现尤为出色。

英文摘要:

Esophageal cancer is among the most common types of cancer worldwide. It is traditionally treated using open esophagectomy, but in recent years, robot-assisted minimally invasive esophagectomy (RAMIE) has emerged as a promising alternative. However, robot-assisted surgery can be challenging for novice surgeons, as they often suffer from a loss of spatial orientation. Computer-aided anatomy recognition holds promise for improving surgical navigation, but research in this area remains limited. In this study, we developed a comprehensive dataset for semantic segmentation in RAMIE, featuring the largest collection of vital anatomical structures and surgical instruments to date. Handling this diverse set of classes presents challenges, including class imbalance and the recognition of complex structures such as nerves. This study aims to understand the challenges and limitations of current state-of-the-art algorithms on this novel dataset and problem. Therefore, we benchmarked eight real-time deep learning models using two pretraining datasets. We assessed both traditional and attention-based networks, hypothesizing that attention-based networks better capture global patterns and address challenges such as occlusion caused by blood or other tissues. The benchmark includes our RAMIE dataset and the publicly available CholecSeg8k dataset, enabling a thorough assessment of surgical segmentation tasks. Our findings indicate that pretraining on ADE20k, a dataset for semantic segmentation, is more effective than pretraining on ImageNet. Furthermore, attention-based models outperform traditional convolutional neural networks, with SegNeXt and Mask2Former achieving higher Dice scores, and Mask2Former additionally excelling in average symmetric surface distance.
